Anatomy - other kinds of pressure

urine, kidney, nephron, you know the deal! (mod. 17)

What is capillary exchange influenced by

Osmotic/hydrostatic pressure

Hydrostatic pressure

pressure of fluid against container

Osmotic pressure

forced needed prevent water movement

High osmolarity =

high osmotic pressure

nephron part that helps w/water/glucose/sodium reabsorption

Proximal tubule

What kind of pressure should be LOWER on capsule side

osmotic

What kind of pressure should be GREATER on capsule side

Hydrostatic

Water recovery happens in

Collecting ducts

BP decrease. Blood vessels in kidney ___ for steady filtration

RELAX

look over

looked.

when is ONLY CASE red blood cells present in filtrate (urine)

Kidney damage present

What helps w/protein metabolism

Urea/ammonium

Nucleic acid metabolism?

Uric acid

Kidneys filter entire blood plasma (___ L) through capillaries to ____ 60 times a day! OVER _____

3 Liters, proximal tubule, 180 LITERS

WHAT ELSE does proximal tubule do

remove nitrogenous waste

JGA (juxtaglomerular) influences arteriole diameter based on ____

filtrate concentration

Renin Angiotensin Aldosterone System

helps with BP and GFR

Afferent arteriole vasoconstriction

GHP decreases, GFR decreases

Efferent arteriole vasodilation

GHP DECREASES, GFR DECREASES

Afferent arteriole vasodilation

GHP INCREASES, GFR INCREASES

Efferent arteriole vasoconstriction

GHP increases, GFR increases

What blood vessel connects glomerulus to peritubular capillaries (aka capsule)

efferent arteriole

What vessel associated with cortical radiate artery (Hint: coming INTO glomerulus)

Afferent arteriole

WHERE do hydrogen ions leave (hint: nephron)

Distal convoluted tubule/collecting duct

What do JG cells do

Change vessel diameter AND renin release for BP

What does renin do

INCREASE filtration rate through RAAS
